Being able to say “OK Google” from the comfort of your home screen was introduced alongside the Nexus 5′s Google Experience Launcher a few months ago. It allows users to control their devices with just their voice, as saying “OK Google” launches the voice command detection mode. With the newest update of Google Search, “OK Google” can finally detect languages other than English, and it works perfectly fine with other devices, but a little “hack” is needed.
XDA Recognized Developer memnoc wrote a handy guide describing how to activate this functionality on a device other than the Nexus 5. The hack isn’t overly complicated, and all you need is root access and a decent file manager.
The method is a chain of copy-paste operations and one simple bin file edit. The described method should work on all devices with Android 4.4.2, and was confirmed on the Nexus 5, Nexus 4, and HTC One S—and even non-AOSP ROMs are supported. It’s definitely great that the hot word detection is finally available for other devices and languages, as not everybody can speak English with a perfect accent.
If you have Android 4.4.2 on your device and want to speak to your device, go to the guide thread, follow the steps, and enjoy your device’s newly found abilities._________
